Review on biological mechanic research development of ankle plantar flexion and dorsiflexion
背屈肌群的生物力學研究進展 -
To investigate the the body shape strength and kinematics that effects sprint expert performance 17 healthy male sprinters were measured using songxiam9000 high speed vidicon in the field ; body shape of sprint athlete were tested by steel rule ; meanwhile shoulder were tested at 60, 240and360 deg / sec velocities ; lower limb were tested at 60, 240 deg / sec velocitues using biodex - ii tesing and rehabilitation system in the laboratory this research provide theoretical basement to scientifically make reasonable exercise prescription and perfect sprint theory the result show that ( 1 ) the results of correlation indicate that 100m performance related to the shoulder fast flexion torque and hip flexion / extension torque ^ ankle fast dorsiflexion torque ; ( 2 ) the upper arm relaxing enclose and lower limbs length effect 100m performance ; ( 3 ) the biggest shoulder extension joint, swing rage of shoulder and the biggest elbow joint extension effect 100m performance
受試者為17名男子一、二級短跑運動員。使用松下m9000高速攝像機對100米跑動過程中的運動員進行錄像，同時測試短跑運動員100米成績，利用愛捷錄像分析系統獲取運動學參數；用人體測量尺測試短跑運動員的肢體圍度；同時採用biodex -型等動測力及康復統，測試運動員上肢肩關節及下肢髖、膝、踝3個關節的等速屈伸肌力。在角速度60 s （慢速） 、 240 s （中速）和360 s （快速）下測試肩關節等動向心收縮肌力；在角速度60 s9慢速）和240 s （快速）及120 s下測試下肢3關節等速向心及離心肌收縮肌力。 -
Results : the results showed that children had similar adaptation features as adults that they adjusted to treadmill walking with shorter stride lengths, shorter single - support phases, longer double - support phases, greater hip flexion and ankle dorsiflexion at heel strike, smaller variability of intra - limb coordination and higher physiological costs than during overground walking ( p < 0. 005 )
結果：研究結果顯示兒童和成人有相似的適應特色，他們在跑步機上行走時會比在地面上行走時以較短的步長、較短的單腳支撐期、較長的雙腳支撐期、于腳跟著地時有較大的髖關節彎曲和踝關節背曲角度，較小關節間協調之變異性以及比較高的生理消耗來適應。
